Chrome Local Overrides [Snowball Showdown - Sans Holiday Hack 2024]

Chrome dev tools have a really neat feature called Overrides where I can set up a local copy of a file that a website requests and have that served instead of asking the server for a copy. This allows me to tweak JavaScript, images, HTTP headers, whatever I would like. In this video I'll show this feature and how to use it to solve the Snowball Showdown challenge in the 2024 SANS Holiday Hack challenge.
